In git master, that would be the Telit plugin itself managing the QMI
modem, that's what I was suggesting. In 1.4.12, yeah, could be the
Gobi plugin or directly the Generic one which both have QMI support.

As long as the plugin managing the modem is a QMI based one, yes, you're good.

Actually, why don't you try to get the modem fully connected manually
with qmicli or qmi-network and see if you still see the same issues
when ModemManager's logic is not around?
